The Chinese word "专栏" is formed through the semantic combination of two characters: "专", which conveys the idea of specialization or expertise, and "栏", which denotes a column, section, or partitioned area. Together, they create a compound meaning where "专" modifies "栏" to specify a column that is dedicated to a particular subject, often seen in media contexts like newspapers or magazines as a featured or specialized section. This formation relies on the direct merger of meanings from each character to express a unified concept, illustrating a common method in Chinese word construction where individual meaningful units are joined to convey more specific ideas.
